Command-Line Arguments Not Recognized by PETSc.Options/uw.options

[gthyagi]

I'm encountering an issue where the command-line arguments passed to the script are not being recognized by PETSc.Options. Specifically, when running the script with python3 Example.py --case case4, the provided argument is not recognized. This is not getting updated

options = PETSc.Options() 
case = options.getString('case', default='case1') # uw.options.getString('case', default='case1')

Had the same issue (#210) just remove the PETSc import. UW handles the options now, no need to import PETSc

I initially tried using uw.options, but it didn't work. I then switched to using PETSc.Options, but that didn't resolve the issue either.

This should work:

import underworld3 as uw

res  = uw.options.getInt("res")

print(f'res = {res}', flush=True)

from the command line:

python3 test.py -uw_res 5

should print 'res = 5' in terminal.

You may be missing the -uw_ prefix?

You have to remove/not import from petsc4py import PETSc otherwise it won't work

I'd also remove the default value, so it produces an error and stops the script from running

import underworld3 as uw

res  = uw.options.getInt("res")

python3 test.py -uw_res 5

Thanks @bknight1. This method works, but I'm planning to create a single .py file that can run both as a notebook and on NCI. If I can't set a default value, I may need to create two separate .py files.

yeah, you are correct. Adding -uw_ fixes the issue.
Also, I did set default value and ran in parallel on mac. It worked. Hopefully it works without any error on NCI too.
Thanks.
